Lighting devices are described in which the light source comprises a plurality of light emitting structures utilizing the direct conversion of electron energy to photon energy, at high efficiency. Structures are described which will emit color or white light. The lighting devices include thin light sources which emit polarized light in a radiation lobe pattern or as a parallel beam of light, useful for ceiling panels for general polarized nonglare lighting, street lighting, polarized automobile nonglare systems, and long life white light electric lighting lightbulbs with screwin sockets for 120v AC, which are self rectifying. A solar powered street lamp system is also described.
